Title: Photosensitive film and laminating method therefor
Inventor: TSUCHIYA KATSUNORI
IPC: B32B7/02
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a photosensitive film which can sufficiently cover the rough surface state of a substrate without trapping air bubbles by preparing the protective film in such a manner that the surface roughness of the film to be in contact with a photosensitive compsn. layer has a specified or larger arithmetic average roughness in each specified measurement range of cutoff value and evaluation length. SOLUTION: The surface roughness of the face of the protective film to be in contact with a photosensitive compsn. layer is controlled to >=0.5 μm arithmetic average roughness in the measurement range of from 0.08 to 8 mm cutoff value and 0.4 to 40 mm evaluation length. When the surface roughness of the face to be in contact with the photosensitive compsn. layer is less than 0.5 μm in the arithmetic average in the measurement ranges of the cut off and evaluation length above described, air bubbles are easily trapped when the film is laminated on the film. If the roughness is less than 0.1% of the layer thickness of the photosensitive compsn. layer, bubbles are easily trapped when the film is laminated on the substrate, and if it exceeds 50% of the layer thickness, a rough state of the substrate is hardly covered.
